  SAP Error Message:
  
  WRF_ARTICLELIST055 - Error buffering the object
  
  Cause:
  This error typically occurs in SAP Retail (IS-Retail) environments when there is a problem with buffering (caching) article master data or related objects. The buffering mechanism is used to improve performance by storing frequently accessed data in memory. The error indicates that SAP was unable to buffer the requested object, which can be caused by:
  
  Inconsistencies or corruption in the article master data.
  Buffer size or configuration issues.
  Missing or incorrect customizing related to article master buffering.
  Transport or system inconsistencies after a system upgrade or patch.
  Authorization issues preventing proper access to the data.
  Problems with the underlying database or memory allocation.
  
  
  Solution:
  To resolve the WRF_ARTICLELIST055 error, consider the following steps:
  
  
  Check Article Master Data:
  
  Verify the integrity and completeness of the article master data.
  Run consistency checks on article master records (transaction MM03 or IS-Retail specific transactions).
  Look for any recently changed or transported article data that might be incomplete or corrupted.
  
  
  
  Buffer Configuration:
  
  Review the buffering settings in the system.
  Use transaction RZ11 to check parameters related to buffering, such as zbuffer or other custom parameters.
  Check if the buffer size is sufficient and increase it if necessary.
  
  
  
  Clear Buffers:
  
  Clear the SAP buffers to remove any corrupted or stale data.
  Use transaction SM56 or SM12 to check and release any locked buffers.
  Use transaction SM04 or SM66 to check for any user or process locks.
  Use transaction SMLG to manage logon groups and buffer refresh.
  Use transaction SMLT or program RSUSR200 to refresh buffers if applicable.
  
  
  
  Check Authorizations:
  
  Ensure the user or process has the necessary authorizations to access and buffer the article data.
  Use transaction SU53 after the error occurs to check for authorization failures.
  
  
  
  Review Recent Changes:
  
  If the error started after a system upgrade, patch, or transport, review the changes.
  Reapply or correct transports related to article master or buffering.
